Transmitter Cond 7100 e/2(X)H
Conformity with FDA 21 CFR Part 11
In their directive “Title 21 Code of Federal Regulations, 21 CFR
Part 11, Electronic Records; Electronic Signatures” the US
American health agency FDA (Food and Drug Administration) regulates the production and processing of electronic documents for pharmaceutical development and production. This results in requirements for measuring devices used for corresponding applications. The following features ensure that the measuring devices of the Transmitter Cond 7100 e/2(X)H Series meet the demands of FDA 21 CFR Part 11:
Electronic Signature
Access to the device functions is regulated and limited by individually adjustable codes – “Passcodes” (for Passcode Editor see Page 56, overview of factory settings see Page 33).
This prevents unauthorized modification of device settings or manipulation of the measurement results. Appropriate use of these passcodes makes them suitable as electronic signature.
Audit Trail
Every (manual) change of device settings can be automatically documented. For that purpose, each change is marked by a
“Configuration Change Flag”, which can be interrogated and documented via HART communication. Then the changed device settings/parameters can also be retrieved and documented via HART cmmunication.

Safety functions
Hold mode
Display:
The Hold mode is a safety state during configuration and calibration. The loop current is frozen (Last) or set to a fixed value
(Fix).
If the calibration or configuration mode is exited, the
Transmitter remains in the Hold mode for safety reasons. This prevents undesirable reactions of the connected peripherals due to incorrect configuration or calibration. The measured value and “HOLD” are displayed alternately. The Transmitter only returns to measuring mode after enter is pressed and
20 seconds have passed.
Configuration mode is also exited automatically 20 minutes
(timeout) after the last keystroke. The Transmitter returns to measuring mode.
Timeout is not active during calibration.
Behaviour of output signal:
Last: The loop current is frozen at its last value.
Recommended during short configuration procedures.
The process should not change decisively during configuration. Changes are not noticed with this setting!
Fix: The loop current is set to a value that is noticeably different from the process value in order to signal the control system that the Transmitter is being worked at.
For configuration see Pg 51.
30
Transmitter Cond 7100 e/2(X)H
Outputs
Current output / Loop current
The loop current is controlled by the process variable selected in the configuration.
The current beginning and end can be set to represent any desired value. To check connected peripherals (e.g. limit switches, controllers), the loop current can be manually specified (see Pg. 41)
.
HART communication
The Transmitter Cond 7100 e/2(X)H can be remote-controlled via HART communication. It can be configured using a handheld terminal or from the control room. Measured values, messages and device identification can be downloaded at any time.
This allows easy integration also in fully automatic process cycles.
A list of the HART commands can be found in the
“Transmitter Cond 7100 e/2(X)H Transmitter-Specific Command
Specification”: www.mtpro.com/transmitters.
Alarm
The alarm delay is configurable.
Error messages can also be signaled by a 22 mA loop current
(see Configuration, Pg 55).
The alarm LED on the front panel can be configured as follows:
HOLD off: Alarm: LED flashing
HOLD on: Alarm: LED on. HOLD: LED flashing.

Concentration measurement
For the solutions listed above, the Transmitter can determine the substance concentration from the measured conductivity and temperature values in
% by wt. The measurement error is made up of the sum of measurements errors during conductivity and temperature measurement and the accuracy of the concentration curves stored in the Transmitter, see Pg 84 et seq.
We recommend to calibrate the Transmitter together with the sensor, preferrably in the same conductivity range as measured later. For exact temperature measurement, you should perform a temperature probe adjustment.
For measuring processes with rapid temperature changes, a separate temperature probe with fast response should be used.

Information on calibration
Calibration adapts the Transmitter to the conductivity sensor.
Calibration can be performed by:
• Input of cell constant (e.g. for ultrapure-water sensors)
• Determining the cell constant with a known calibration solution
• Sampling (product calibration)
• Temperature probe adjustment
Note:
• All calibration procedures must be performed by trained personnel.
• During the calibration procedure the temperature must be kept constant.
• Incorrectly set parameters may go unnoticed, but change the measuring properties.
Particularly with stray-field sensors the cell constant can strongly vary when the sensor is mounted in restricted space. In that case, the cell constant should be determined with the sensor mounted using a calibration solution or by a reference measurement at the product.

Product calibration
Calibration by sampling
For product calibration the measured variable is used as configured:
Conductivity (µS/cm, mS/cm, S/m), resistivity (M Ω ·cm). During product calibration the sensor remains in the process. The measurement is only interrupted briefly.
Calibration is without TC correction.
Procedure: During sampling the currently measured value is stored in the Transmitter. The Transmitter immediately returns to measuring mode. The calibration mode indicator flashes and reminds you that calibration has not been terminated.
The sample is measured in the lab or directly on the site using a portable meter. To ensure an exact calibration, the sample temperature should correspond to the measured process temperature. The sample value is then entered in the Transmitter. The new cell constant is calculated from these two values. If the sample is invalid, you can take over the value stored during sampling. In that case the old calibration values are stored. Afterwards, you can start a new product calibration.

Sensoface
(Sensocheck must have been activated during configuration.)
The little smiley in the display (Sensoface) provides information about the sensor condition (defects, maintenance required, cable capacitance too high).
It alerts to significant sensor polarization or excessive cable capacitance e.g. caused by an unsuitable cable or a cable that is too long. The permitted calibration ranges and the conditions for a friendly, neutral, or sad Sensoface are summarized in the following chart. Additional icons refer to the error cause.
Sensocheck
Continuously monitors the sensor and its wiring.
Sensocheck can be switched off. Critical values make the
Sensoface “sad” and the corresponding icon flashes:
The Sensocheck message is also output as error message
Err 33. The red LED is lighted, the output current is set to
22 mA (when configured correspondingly). Sensocheck can be switched off during configuration (then Sensoface is also disabled). Exception: After a calibration a Smiley is always displayed for confirmation.
Note:
The worsening of a Sensoface criterion leads to the devaluation of the Sensoface indicator (Smiley becomes “sad”).
To reset the Sensoface indicator, the defect must be remedied and the Transmitter be calibrated.
